Explanation:

Price discrimination can be defined as a pricing strategy whereby customers are charged different price for a similar good or service. In price discrimination, a certain group of customers may be asked to pay a high amount of money while another group will pay a lesser amount.

Price discrimination makes it possible for low income customers to purchase goods at a cheaper price, this is usually achieved from the collection of coupons.

Price discrimination also lowers congestion in the market as it helps to control the demand of a product.
